More and more people are raising backyard chickens, but there’s a lot to consider before proceeding. Did you know that most hens can live 6 or more years (sometimes longer)? And although it does not have to take up a lot of space, does your city allow this and what would your neighbors think? Chicago has no ordinances on this, but even still most people prefer to proceed without a rooster — hens still lay eggs without them. Its also helpful to stick to a regular cleaning schedule for the coop, in the summer things can get nasty, though some food grade Diatemaceous Earth will help keep the bugs, and smell at bay.
